Gear wheel that is provided with spokes () which extend between a rim () supporting a gear mesh () and a corresponding gear hub (), whereby free spaces () are located between the spokes () which extend between the rim () and the gear hub (), characterised in that at least one of said free spaces () is filled with a block () made of a rigid, incompressible material, whereby between the gear wheel () on the one hand and the block () on the other hand a viscoelastic material () is located.

Gear wheel and compressor device equipped with such gear wheel

Multistage centrifugal compressor provided with a shaft with blades, which is mounted in a housing with bearings. At least one bearing is provided with a bearing damper element including a ring arranged between the shaft and the bearing. The ring includes slots through the thickness of the ring in the axial direction (X-X') and at a distance from the radially-directed inner and outer surface of the ring. The slots are at least partially overlapping, and:

Multistage centrifugal compressor

Compressor device provided with at least one compressor element and a drive for the compressor element, wherein all bearings of at least one shaft in the compressor device configured to carry static axial load, are provided with a bearing damper which comprises a coupling element and at least one damping element made of damping elastomer material. The bearing damper is installed with the aid of the coupling element between a bearing of the compressor device and the housing of the compressor device. The coupling element allows little or no movement of the bearing relative to the housing the radial direction compared to the axial direction. The damping element is configured to dampen the axial movement of the bearing relative to the housing.
